Ahhhh, that is the question! I have an old Yamaha a2 amp and recently tried upgrading to the Sony VA555Es to gain the newer sound modes and the 6.1 set up...that is after buying the new speaker, making a mess of the living room installing it, falling off the ladders and nearly breaking my arm!! To cut a long story short, I returned the Sony as the sound (to me) was awful compared to my yammy. Better on music but no where near as warm or powerful on movies - Believe me I did a lot of comparing with my favourite dvds before returning. Anyway I managed to get my money back and forgot about it .... although I keep looking at that additional speaker and wiring I installed and wonder whether I am ever going to get around to hear it! I run a Sony projector VPL11ht and one of the things that has also lured me back to having a little look at changing my amp again is the lip sync delays I keep getting that absolutely do my head in! So....I need a new amp, warm and powerful with lip sync and all of the latest sound modes. I was considering the Pioneer 2011 or the new AX5i although I think the 2011 will do if someone can confim the audio delay (some say yes - some say no). Any other choices? Will I be disappointed with the sound of the pioneer compared to the Yammy ? I know the Denon may be an option but I have the little DM30 set up and whilst it is excellent for the bedroom, to be honest I prefer the warmth of the Yamaha. Does the AZ2 have audio delay? Any advice would be appreciated!
